I agree, but with this massive force called gravity it should never float in the first place.

iT says for something to become a theory that there are rigorous scientific tests that have been done. Where is the beef?

So a flat earh... I am trying to make believe I can believe it so I can try to make sense of it... but I've never had brain damage...
The fact that you can travel in one direction and wind up where you started doesn't matter? Because sure that works if you travel "east-west" as the sun would (or west-east, whichever) but not so much between north and south... as south would either be the edge, or on the other side of the pancake. Or that no one's ever allen of... or that, espit the gimicky photos, if you fly in a plane you always see a rounded horizon anywhich way you look, as does everyone in every other plane in the air at the same time... but not see each other?
Experiment: Let's put four planes at the center of your flat world... then let's fly them out, each in a straight line away from the center, where that line is 90 degrees to the direction of travel of the two planes on either side (like having each traveling towards a cardinal point). If they can keep sight of each other to the edge (using a powerful telescope) and also never meet at the side opposite from where they started (on a globe) then the earth is flat.
I think a better question is, can anyone who takes this seriously prove they're not brain damaged?
Or at least, can you prove you're real? Or If anyone is "real"... the only person I can prove is real is me, and only to myself, but since I'm the only real one, that's perfect.

Okay, but you won't understand them, and it won't do any good...

Tests
The tests of general relativity included the following:[9]
- General relativity accounts for the anomalous perihelion precession of Mercury.[10]
- The prediction that time runs slower at lower potentials (gravitational time dilation) has been confirmed by the Pound–Rebka experiment (1959), the Hafele–Keating experiment, and the GPS.
- The prediction of the deflection of light was first confirmed by Arthur Stanley Eddington from his observations during the Solar eclipse of May 29, 1919.[11][12] Eddington measured starlight deflections twice those predicted by Newtonian corpuscular theory, in accordance with the predictions of general relativity. However, his interpretation of the results was later disputed.[13] More recent tests using radio interferometric measurements of quasars passing behind the Sun have more accurately and consistently confirmed the deflection of light to the degree predicted by general relativity.[14] See also gravitational lens.
- The time delay of light passing close to a massive object was first identified by Irwin I. Shapiro in 1964 in interplanetary spacecraft signals.
- Gravitational radiation has been indirectly confirmed through studies of binary pulsars. On 11 February 2016, the LIGO and Virgo collaborations announced the first observation of a gravitational wave.
- Alexander Friedmann in 1922 found that Einstein equations have non-stationary solutions (even in the presence of the cosmological constant). In 1927 Georges Lemaître showed that static solutions of the Einstein equations, which are possible in the presence of the cosmological constant, are unstable, and therefore the static universe envisioned by Einstein could not exist. Later, in 1931, Einstein himself agreed with the results of Friedmann and Lemaître. Thus general relativity predicted that the Universe had to be non-static—it had to either expand or contract. The expansion of the universe discovered by Edwin Hubble in 1929 confirmed this prediction.[15]
- The theory's prediction of frame dragging was consistent with the recent Gravity Probe B results.[16]
- General relativity predicts that light should lose its energy when traveling away from massive bodies through gravitational redshift. This was verified on earth and in the solar system around 1960.

Since you are new, take a look at this, the sun makes its way around the earth, north is the center east and west are the circular lines. As long as the compass is always pointing north you can make your way around the flat plane just fine just like the sun does in the image.
Here is a video of the moon from an amateur rocket while the moon was over australia, taken from nevada. impossible on a ball earth. The earth should have been blocking this as Australia is on the other side of the supposed planet.

More about Earth's Gravity from the same link -
Earth's gravity
Main article: Earth's gravity
Every planetary body (including the Earth) is surrounded by its own gravitational field, which can be conceptualized with Newtonian physics as exerting an attractive force on all objects. Assuming a spherically symmetrical planet, the strength of this field at any given point above the surface is proportional to the planetary body's mass and inversely proportional to the square of the distance from the center of the body.
If an object with comparable mass to that of the Earth were to fall towards it, then the corresponding acceleration of the Earth would be observable.
The strength of the gravitational field is numerically equal to the acceleration of objects under its influence.[citation needed] The rate of acceleration of falling objects near the Earth's surface varies very slightly depending on latitude, surface features such as mountains and ridges, and perhaps unusually high or low sub-surface densities.[20] For purposes of weights and measures, a standard gravity value is defined by the International Bureau of Weights and Measures, under the International System of Units (SI).
That value, denoted g, is g = 9.80665 m/s2 (32.1740 ft/s2).[21][22]
The standard value of 9.80665 m/s2 is the one originally adopted by the International Committee on Weights and Measures in 1901 for 45° latitude, even though it has been shown to be too high by about five parts in ten thousand.[23] This value has persisted in meteorology and in some standard atmospheres as the value for 45° latitude even though it applies more precisely to latitude of 45°32'33".[24]
Assuming the standardized value for g and ignoring air resistance, this means that an object falling freely near the Earth's surface increases its velocity by 9.80665 m/s (32.1740 ft/s or 22 mph) for each second of its descent. Thus, an object starting from rest will attain a velocity of 9.80665 m/s (32.1740 ft/s) after one second, approximately 19.62 m/s (64.4 ft/s) after two seconds, and so on, adding 9.80665 m/s (32.1740 ft/s) to each resulting velocity. Also, again ignoring air resistance, any and all objects, when dropped from the same height, will hit the ground at the same time.
According to Newton's 3rd Law, the Earth itself experiences a force equal in magnitude and opposite in direction to that which it exerts on a falling object. This means that the Earth also accelerates towards the object until they collide. Because the mass of the Earth is huge, however, the acceleration imparted to the Earth by this opposite force is negligible in comparison to the object's. If the object doesn't bounce after it has collided with the Earth, each of them then exerts a repulsive contact force on the other which effectively balances the attractive force of gravity and prevents further acceleration.
The force of gravity on Earth is the resultant (vector sum) of two forces: (a) The gravitational attraction in accordance with Newton's universal law of gravitation, and (b) the centrifugal force, which results from the choice of an earthbound, rotating frame of reference. At the equator, the force of gravity is the weakest due to the centrifugal force caused by the Earth's rotation. The force of gravity varies with latitude and increases from about 9.780 m/s2 at the Equator to about 9.832 m/s2 at the poles.

These experiments are based on a false assumption. The assumption that we are living on a ball.

Those experiments work because we are living on a ball. They wouldn't work otherwise. *Drops Mic* /Thread...

'‘But the whole universe is outside us. Look at the stars! Some of them are a million light-years away. They are out of our reach for ever.’
‘What are the stars?’ said O’Brien indifferently. ‘They are bits of fire a few kilometres away. We could reach them if we wanted to. Or we could blot them out. The earth is the centre of the universe. The sun and the stars go round it.’
Winston made another convulsive movement. This time he did not say anything. O’Brien continued as though answering a spoken objection:
‘For certain purposes, of course, that is not true. When we navigate the ocean, or when we predict an eclipse, we often find it convenient to assume that the earth goes round the sun and that the stars are millions upon millions of kilometres away. But what of it? Do you suppose it is beyond us to produce a dual system of astronomy? The stars can be near or distant, according as we need them. Do you suppose our mathematicians are unequal to that? Have you forgotten doublethink?’'

I'll take that as a victory then. It's okay, god may still exist even when you realize the Earth is not flat. Many xians believe the Earth is round...

Imo, the greatest aspect of scientific theory is that it not only explains, but predicts. You can feel that you are on the right track when we discover just what theory predicts we will. It's almost magical. There is no other methodology that can routinely predict with accuracy. The scientific method is a great tool, one worth the time and effort to understand...

So I'll try again... traveling AS IF using the cardinal directions... technically our imaginary planes are on the north pole, technically, in our flat earth model, they will all be traveling south in different directions, away from the center... now they either hit the edge, each plane at a different point along that edge, or they meet at the diametrically opposite side of the round earth.
Just in case: draw a clock on your flat earth map, where the top is 12, right is 3, bottom 6, left 9... if each plan travels towards one of those points... they either wind up the diameter distance of the circle away from each other (on a flat circle) or they wind up meeting up, at the opposite side of the world.
Is that better?

Flying a plane there's only one horizon... where "sky" appears to meet Earth (not dirt, planet, so oceans too)... what I see in that pic is a false horizon of clouds... which means bupkiss.
